SEAT-SPRING.

Specification of Letters Patent. Patented Sept. 26, 1916.

Application filed March s, 1916. Serial No. 82,859.

To all whmh it may concern.-

Be it knhwn that I, CHARLES O. ORMSBEE,. a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Seat-Springs, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyin drawings, which form a part of this specld'ation.

This invention relates to springs and upholstering, and comprises a border strip of the channel type arranged to both hold the spiral springs and the lower edge of the upholstering.

In the drawings-Figure 1 is a side elevation of a fragmentof an automobile seat cushion. Fig.2 is a fragmentary view looking down on the top of the border strip; that portion of the view at the left'showing the border strip stamped over, the upholstering skirt, while that portion of the view at the right shows the strip ready to receive the upholstering skirt. Fig. 3 is a vertical cross section on'the line A-A of Fig. 1. Fig. 4 is a vertical cross section on the line 13-13 of Fig. 1. but omitting the doubled-in lower flange of the channel strip,-this being an alternative construction.

a designates the upholstering facing or skirt; 1) the spiral springs, and c the border strip. The border strip is a channel strip which may or may not have thelower flange (I doubled backupon itself. Fig. 3 shows the lower flange doubled in and Fig. 4 shows right side of Fig. 2. The remaining major ortion of the upper flange of this strip is eft in the position shown at the right of Fig. 2. In this position the strip forms anupwardly opening groove to receive the lower edge of the upholstering facing a,

which is ordinarily provided with a cord f. The trimmer may place this lower edge of the upholstering facing in this upwardly opening groove and then pinch the upper flange down over the upholstering facing and cord f in the manner shown in Fig. 4 and at the left in Fig. 2.

I am aware that it is old to use a border I nel, strip both to secure theuipholstering' facing and the spiral springs, thereby effecting considerable saving in material.

What I claim is:

1. In a seat cushion, aborder strip in the form of a channel strip having an inwardly opening groove and having portions of the upper flange struck in and turned over to form clips to secure the lower coilsof the spiral springs and the remaining portions o'fthe upper flange being arranged to be turned in to secure the. upholstering facingedge.

2. In a seat cushion, a border strip comprising a channel strip having an inwardly opening groove and its lower flange doubled back. upon itself, portions of the upper flange being struck out to he turned down over the lower coils of the spiral springs to form clips for securing the same to the border V strip and the remaining major portion of the upper flange of the strip forming an upwardlyand inwardly facing groove to receive the lower edge of the upholstering facing which may be secured to the border strip by pinching such remaining major portions of the upper flange thereover.

In testimony whereof, I sign this specification.

CHARLES O. ORMSBEE.
